Topic: MPG - cb550 motogpwerks pipes

[goldarrow]

Seeing many if you have these pipes, curious to hear how much mpg you guys get in your 550 bikes, 750 bikes are also welcome. 

I get about 30mpg on my 550.

[LesterPiglet]

Holy #$%* that's terrible. I don't think your exhaust is using 10+ MPG.


Ahhh, US gallons. I need to go away and do some conversions. Stop bloody changing stuff America.

I didn't want to think that either but I have 110 main jets in the carbs...

[Stilltime]

When riding solo, I was getting ~45mpg last summer, with 105's and SDP velocity stacks.  Needle unchanged in my PD46C's, and idle mixture richened slightly.

[Stev-o]

That is terrible, you should take that pipe off and sell it to me!

I don't play that "how many MPG..." game, I do everything wrong that is told to get get fuel economy (accelerate fast, speed, etc)

If I used my bike for commuting it would be different.

Been thinking bout going back to stock pipes, but don't know...

Probably wouldn't care so much if riding for leisure, but yeah I do commute on all my bikes, so 40 mpg is nice number

[alacrity]

I am getting 44mpg.
see my signature line thing to see how the bike is setup

Seems like 550's often get worse mpg than 750's.  I have heard of many 550 guys reporting mpg figures in the high 30's.  30mpg even?...that is bad and I wouldn't think any pipe would cause mileage that bad.  My guess is you have a combination of hidden problems such as slightly rich jetting, mildly defective ignition, incorrect tire pressure, worn wheel bearings, worn drive chain, or some combination of some of these.  I have not had my 550 long enough to check mpg.  My 750 gets anywhere from 42 to 48 mpg depending on riding style and how many hours I left my bike sitting with the petcock on.

40 mpg for me no matter what I do to the bike.

Have changed from a MAC 4 into 1 to a 550f pipe. Have always run the Tintop intake. Currently running 120 mains and 40 pilots but she is still a bit lean. If I can ever get the bike out of storage, I can work on that.

[goldarrow]

I was getting about 35mpg prior to this, but felt a bit lean on the midrange so I adjusted the clips. At the same time, I've also been chasing low throttle richness problems.  Just wanted to get you guys input to see if 40mpg can be achieved with these pipes.

My other bikes 550s and 750s in stock configuration get 40mpg on average.   95 miles of cruising 70-80mph on freeway, WOT when going uphill

Yeah,  agree about 550 mpg- my 750 returns 45, my 400 from 50-55, but my pretty stock 550 is in the 35-ish region. 

[LesterPiglet]

My stock 550 will do 10 miles per liter and I am not economical. This works out to be around 39 MPG US.

[iron_worker]

Miles / liter?

lol

I guess the ODO reads in miles and the gas station probably reads in liters ... so makes sense .... sort of.

You are correct. We deal in miles. The pumps deliver liters. The rigmarole I went through to then convert to US gallons.   

[Bankerdanny]

That strikes me as very low. Even when I was commuting in Chicago traffic my completely stock '77 550K managed low 40's at worst. On the highway 47-48 consistently and I even broke 50 once.

[Mooshie]

My 550 gets 50+ mpg consistently on highway and 45-48 on twisties.  I love my 550

You have less weight to carry though.

Very impressive numbers.  Make me depress at the same time.  Lol.  I gotta get those carbs adjusted.

[Pat_at_APE]

My CB550F gets mid 30's and my CB750F gets high 40's average MPG.

Hi Mooshie....what exhaust do you have, Jardine? Looked at the calendars but do not recognize it.

[Bankerdanny]

Yes, I imagine the 100 extra pounds or so that my bike had to carry probably had some impact on mileage. LOL

Awww, aren't you all sweet.  This is the only place where I get that type of a response!   Oh, and I am running pods as well--Kott Motorcycles knows how to tune and jet carbs for these bikes that is for certain.  I have no idea what type of mufflers/pipes I have.  I will take a closer look when I get home.

PODS!!??? On a 550!!?? GASP!!! Girl, don't you know that Pods invert the flux turbulence pattern induced by the stock airbox?? 
How many miles have you logged with pods so far, Lisa?

[FunJimmy]

How many miles have you logged with pods so far, Lisa?

Many.

"Kott Motorcycles knows how to tune and jet carbs for these bikes that is for certain." While they may be able to tune carbs can they show me a before and after dyno run with pods being the only change and it made more power than stock? It may run fine and dandy but better than the stock air box I have my doubts. I am still waiting after 15 years for someone to post proof that they got pods to work better than a properly tuned stock air box.
